    well for question 4, there are students and adults on a bus. so number of students + number of adults = number of people on the bus. right? so 20+ number of adults = 35 and now you just have to find the number of adults

    Inequalities are solved like equations with a few rules. Some rules apply where you have to change the sign...< turns to > and vice versa. Like equations, you try to get the variable on one side and everything else on the other side. Rules : (1) adding or subtracting the same number on both sides does not change the sign. Even if both numbers are negative. (2) multiplying/ dividing a POSITIVE number on both sides does not change the sign. (3) multiplying / dividing by a NEGATIVE number on both sides CHANGES the inequality sign 1. m - 7 < 6 (add 7 to both sides of the < sign) m - 7 + 7 < 6 + 7 (combine like terms) m < 13 ===answer 2. n - 8 > 5 (add 5 to both sides to get n by itself) n - 8 + 8 > 5 + 8 n > 13 ===answer 3. p + 5 < 10 (subtract 5 from both sides to get p by itself) p + 5 - 5 < 10 - 5 p < 5 ===answer 4. s stands for students c stands for chaparones s + c < or equal to 35 s = 20 now substitute 20 in for s in the inequality... s + c < or = 35 20 + c < or = 35 (subtract 20 on both sides to get c by itself) 20 - 20 + c < or = 35 - 20 c < or = 35 - 20 c < or = 15 ===answer The reason I wrote this as an inequality is because it does not say there will be 35 people on the bus, it says " at most " 35 people. This means it is not a definite number. It means 35 or less people. This means it is = or <( less) then 35. I hope I could help you understand this better :)
